Equipment For Producing Float Plate Glass

The present invention provides an equipment for producing a float plate glass. The equipment for producing the float plate glass is characterized by comprising a fusing groove arranged adjacent to an opening part arranged on the upper-layer floor of a building; a bath groove for shaping the fused glass float into a glass belt; a main pipeline arranged in the lower layer of the building, and possessing a plurality of injection pipes opposite to the bottom of the bath groove; a master air blower; a clathrate floor arranged at the lower side of the bath groove and forming an intermediate layer; a supply pipe penetrating the clathrate floor along the upper and down directions, extending to the bottom of the bath groove, and possessing the injection pipes at the top end side; a plurality of slave air blowers arranged on the clathrate floor, and conveying the air surrounding the supply pipe to the lower layer side below the fusing groove via the clathrate floor. The equipment for producing the float plate glass is equipped with an exhaust stream path which conveys the air conveyed to the lower layer side below the fusing groove to the upper layer via the opening part and then exhausts the air to the exterior of a room.
